SPEEIDER MECHANISM FOR MOTOR-BOATS.

Specification of Letters Patent.

Patented Sept. at, 1917.

Application filed February 12, 1917. Serial No. 148,069.

To all whom it may concern:

Be it known that I, WILEY J oNns, a citizen of the United States, and resident of VVesterly, in the county of Fayette and State of l/Vest Virginia, have invented certain new and useful Improvements in Speeder Mechanism for Motor-Boats, of which the follow ing is a specification.

This invention relates to marine propulsion, and more specifically to a speeder mechanism for motor boats. p

The object of my invention is to provide a mechanism whereby the propulsive power will bedirected to the prow of a boat both forwardly and upwardly, instead of against the engine in the rear of a boat as motor boats are at present constructed. The forward force of the propulsive power as clirected to the prow of the boat by my mechanism removes all forward pressure from the 7 engine, thus making the engine run more freely and easily due to lessened frictional engagement; it also greatly lessens the wear and tear on the engine. The upward force of the propulsive power tends to raise the prow of the boat from the water, thus lessening frictional engagement in its progress and greatly increasing the speed of the craft in proportion to the energy utilized,

Other, objects of this invention not at this time more particularly enumerated, will be clearly understood from the detailed description and drawings forming a part of this specification.

Furthermore, this invention consists in the novel arrangement and combination of parts more particularly described in the following specification and embodied in the claims appended hereunto and forming a part of this application.

Referring now to the drawings, which are merely illustrative of my invention;

Figure 1 is a longitudinal sectional view through a boat equipped with my speeder mechanism;

Fig. 2 is a horizontal sectional view of the same taken on the line 22 of Fig. 1;

Fig. 8 is a detail top plan view of my sliding universal joint;

Fig. i is a side elevation of the same.

Referring further to the drawings, wherein similar reference characters designate similar parts throughout the respective views, 1 designates the hull of a boat while 2 is an. engine mounted therein, said engine be ing provided with the customary main shaft 3 and fly-wheel a. Upon the rearward end of said main shaft 8 is mounted a sliding universal joint 5. Said sliding universal joint is constructed of a metal piece centrally disposed with respect to bifurcated members 6 fixed to both ends thereof, each prong of said bifurcated members being provided with a slot parallel to a similar slot in the opposite prong. A sliding pin 8 is secured transversely through the end of the main shaft 3, said pin being adapted to have a reciprocating movement within the slots 7 of one of the bifurcated ends of joint 5, while a sliding pin 9 is secured transversely near the inner end of the propeller shaft 10 and is adapted to have a reciprocating move ment within the slots 7 of the opposite bifurcated end of joint 5. The outer or rearward end of the propeller shaft 10 has mounted thereon a propeller 11. A collar 13 is adjustably mounted by means of a set screw 14 upon the propeller shaft 10. Forward of said collar 13 and surrounding the shaft 10 is an oil boxing 12, wherein said shaft may revolve freely and may also have a reciprocating movement. Integral with the transverse sides of said oil boxing 12 are fixed oppositely extending arms 15 whose ends project through upright guide members 16 mounted upon the floor of the boat. A clevis 17 is fixed to the free end of each arm. Speed bars 18 are mounted to said clevises by means of rigid joints 19. The said speed bars may be bent to conform to the shape of any particular boat to which my mechanism is fitted, though the usual construction is to have them extend outwardly and forwardly a certain distance, thence forwardly and upwardly on both sides of the boat to a point near the top of the prow thereof, where the ends of the said speed bars are secured at 20.

In revolving the propeller for movement of the boat forward, the propeller shaft being slidably mounted upon the sliding universal. joint 5, which in turn is slidably mounted upon main shaft 3, the said propeller shaft is caused to move forward within oil boxing 12. Such forward movement of the propeller shaft is arrested when the collar 13 contacts with the oil boxing, which also serves as a bearing for transmitting the forward pressure of the propeller to the arms 15, thence to the speed bars 18 which. by reason their shape and the point the boat where the ends are secured, receive a pressure both forward and upward at the prow of the boat.

The utility, adaptability, and advantages of my improved form of speeder mechanism for motor boats being obviously apparent, it is unnecessary to further enlarge upon the same herein. I I

Having now described and pointed out the new and useful features of my invention, I do not limit myself to the shape of certain parts where the shape is not essential, nor do I restrict myself to the exact details of construction shown and described, but mean and intend to claim all equivalents and Variations thereof not departing in principle from my invention and falling within the purview of the appended claims.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a device of the kind described, the combination of a boat, an engine mounted in said boat adapted to revolve a propeller shaft, means interposed between said propeller shaft and. the main shaft of said engine whereby said propeller shaft may have horizontal reciprocating movement, crossarms slidably mounted upon said propeller shaft, a collar adjustably mounted upon said propeller shaft rearwardly of said crossarms, and forwardly and upwardly eXtending speed bars mounted at one end to the ends of said arms and at the other end to the prow of the boat.

2. In a speeder mechanism for motor boats, the combination of a boat, an engine mounted in said boat, a main-shaft adapted to be rotated by said engine, a propeller shaft, a coupling connecting said main-shaft and said propeller shaftwhereby they may be rotated at an angle to each other, means forming a part of said shafts and said coupling whereby said propeller shaft may have reciprocating movement forwardly and backwardly, means adjustably mounted on said propeller shaft whereby said reciprocating movement forwardly may be regulated, cross-arms slidably mounted about said propeller shaft forwardly of said lastnamcd means, means connected to said crossarms and to the prow of a boat whereby forward propulsive force will be directed to the prow of the boat.

In testimony whereof, I aflix my signature hereto.

W'ILEY JONES.
